Diagnostic value of ultrasonography in necrotizing enterocolitis:a meta-analysis / 中国新生儿科杂志

ABSTRACT

Objective To evaluate the diagnostic value of ultrasonography in neonatal necrotizing enterocolitis (NEC)by Meta analysis.Methods PubMed,EMbase,CBM,CNKI,VIP and WanFang databases were retrieved to incorporate studies on the diagnostic value of ultrasound in NEC that met the inclusion criteria.The retrieval time limit was from establishment of the databases to July 24th,2015. QUADAS was used to assess the quality of the literatures and Meta -Disc software (Version 1 .4)was used for Meta analysis.The SROC was drawn and the area under curve (AUC)of SROC was calculated.Results A total of 7 studies were included and 485 patients were involved.The sensitivity of the ultrasonography was 0.65 (95%CI 0.58 ~0.71 )and the specificity was 0.61 (95%CI 0.55 ~0.67).The AUC of the SROC was 0.726.Conclusion The ultrasonography showed no clear advantage for diagnosis of NEC.Combining with clinical manifestations would enhance the diagnostic ability of the ultrasound.
